Question

Quizplus · Accepted Answer

Vanessa's belief that she sleeps better with music may be confounded by other factors, such as her level of distraction or the time that she goes to bed. By noticing that she only remembers to use her iPod on nights when she finishes studying earlier, Vanessa may be falsely attributing the cause of her improved sleep to music, rather than these other factors. Therefore, choice A is the best answer because it suggests an alternative explanation for Vanessa's improved sleep.
